Answer

n + 1

Explanation

The number of lines of rotational symmetry is the number of rotations plus one.

\begin{align*}\eqalign{

\text{Lines of rotational symmetry} &= \text{number of rotations} + 1 \\

\text{Lines of rotational symmetry} &= n + 1

}\end{align*}

If a figure can be rotated n times, it has n + 1 lines of rotational symmetry.
